I am trying to make a program that will calculate gpa using a transcript from an input file. The transcript includes the title of the subject, the letter grade, and the credits per class. However, I wouldn't know how many courses are in the file. How would I start to write out this program? The only things I can use are ifstream, ofstream, for-loops, if statements, and if-else statements.
View 3 RepliesOne of my class assignments is to create a program that receive a .txt file containing a students name and their grades as follows:
John K. 99, 87, 57, 89, 90, 95
Amanda B. Jones 100, 88, 76, 99, 86, 92
etc..
The number of students is unknown until run time. You have to take those grades and average them weighing the first (4) at 10% a piece and the last (2) at 30% each.
Then return an output file with the students name and their letter grade A,B,C,D,F based on their computed score. In addition, on screen it needs to display the average scores for each Q1, Q2, etc. as well as the minimum and maximum for each test on the screen. I am having a hard time in assigning the scores to a variable so that they can then be computed as an average and then used to determine a letter grade. I have begun to write the code and am a bit stuck..here's what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
[Code]....
I need my program to read a list of numbers from and input file, random.txt, and calculate the following statistics on those numbers:
A. The number of numbers in the file.
B. The sum of all the numbers in the file.
C. The average of all the numbers in the file.
D. The largest number in the file.
E. The smallest number in the file.
#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
[Code]......
This is what I have so far but I'm not sure if it is right. I can't get the input file to open.
I added my assignment to attachment, i need to calculate the sum for input values of x and n this is my code:
#include<stdio.h>
#include<math.h>
main() {
float gore,dole,s,x;
int n,i,j,z;
s=0;
i=0;
j=0;
[Code] ....
gore calculates x^(2*i)-3 and dole is for (2+i)! for input x=1 and n=1 i get -2.0 output which is the value of x^(2*i)-3 the (2+i)! part gets ignored for some reason, for any other input i tried the output is 0 ....
I need starting a do-while loop in my program that runs up to 10 time that asks the user to enter up to 10 scores, which include the slope and rating for the course, and calculates the handicap for each score. Here's what I have so far:
//This program calculates a golfers handicap.
#include <iostream>
#include <string>
using namespace std;
int main(){
int score, slope;
double rating, handicap;
[Code] ....
This is my code and it's not giving me the right output
Code:
#include <stdio.h>
int main() {
int dim;
int i, row, col;
// inputting matrices dimensions
int M0, M1, M2;
[Code] ....
The output should give me this:
Input 2
Correct Output 2 5 4 10
I am trying to create a program that will calculate pi based on a user input for accuracy. If the user input .3 then when the leibniz infinite sum value at a particular i becomes less then the input of .3 then the loop will exit.
I have looked at a number of examples on the internet but I feel lost. I have put together working code that will infinitely output sums but I need the loop to stop when the sum value is less then the accuracy value.
My question is what is wrong with my while loop, why will it only give me infinite summations? How do I make it so that the loop will exit when my accuracy input is greater then the sum?
int main () {
double accuracy;
cout<<"Give an accurate number." << flush;//looks nice
cin>>accuracy;
int d;//initialize denominator
double pi = 0.0;
while(accuracy < d){

I'm trying to create a program that will take input from a user and calculate it in a do-while loop. The program does the calculation but the answer is wrong. The loop also doesn't work. The purpose of the program is to see how much an item will cost after a discount is taken off and tax is added.
#include <iostream>
#include <cmath>
using namespace std;
double original_cost;
double discount;
double tax;
double total;

I have created a program to calculate different measurements for a cylinder. Anyways, the end user has to input 3 variables.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
The numbers are what "End User" would input. But I need to make it look like this when said "End User inputs the numbers.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
Here is what I have for it, but I don't know what to put where.
printf("
Enter the lower radius: ");
scanf("%f", &lower_rad);
printf("Enter the upper radius: ");
scanf("%f", &upper_rad);
printf("Enter slant height: ");
scanf("%f", &slant_h);
I'm still fairly new to c++ and am having trouble with dynamic arrays. My task is to create an array for test scores. The user needs to define the size of the array and then input data to later sort and calculate the average.
Below is what I have so far. I am struggling with the user input part. I receive the following errors for the data input of the individual scores:
"error C2108:subscript is not of integral type"
"IntelliSense:expression must have integral or unscoped enum type"
Code :
#include<iostream>
#include<iomanip>
using namespace std;
int main() {
//user input total number of scores
cout<<"Please enter the total number of test scores."<<endl<<endl;
[Code] ....
I have this code that im stuck on what i need to do is Extend the code such that when it starts the user is asked to input values to specify each of the three ranges before moving on to accept and tally the main values how do i do that Using a for loop to input and output array values Also calculate the average
*/
#include <stdio.h>
int main(void)
{
/* Declare an array of integers */
int Grades[5];
int nCount;
int nTotal = 0; /* Declare and initialise the value */
float fAverage;
[Code]...
So I have to make a program that allows the user to enter both positive and negative numbers and the program is suppose to calculate the sum of only the positive values while ignoring the negative values. Also it is to be a sentinel-controlled loop with a number ending the set of values.

If the percents dont add up to 1 (i tell the user to enter the decimal value) I set up and if statement to catch it and end the program. Except that if i type in
Assignments = .3
Midterm1 = .3
Midterm2 = .3
Finals = .1
the program doesn't recognize that they add up to 1. Heres the relevant portion of my code [URL] ....
Here's some examples of how it works [URL] ....
And heres what i dont understand [URL] ....
Why is it saying .3 + .3 + .3 + .1 != 1 when .1 + .3 + .3 + .3 == 1?
I have tried writing a code which takes two numbers from the user and calculates their square root then the roots are added up to return the sum. The program is coming out with loads of errors.

float main(){
using namespace std;
float m1,m2,m3,m4,m5;

I'm trying to make a c++ program of this but i don't know how to use the bubble sorting.
Write a C++ application that asks the user to enter 10 numbers. The program then stores those numbers in an Array. The program should display the Mean , Median, and Mode.
Mean is the average of the 10 numbers.
Median is the average of the 5th and the 6th numbers. (But you have to arrange the numbers in ascending order first using Bubble Sort before calculating the Median.)
Mode is the most frequent number among the 10 numbers.
i have a text file... with example following content:
Pizza 23232
Car 44,495
Drink 3493,90494
....
..
.
and so on..
no i want to find the 44,495 in this textfile.. calculate a new value like 44,495 x 2 + 5
and write the same file as
Pizza 23232
Car 93,99
Drink 3493,90494
....
..
.
back..
I have written two separate programs; Program 1 calculates the average of an array of numbers which has been hard-coded into the program. Program 2 reads an array of numbers from a text file and displays them on the output.
I wish to combine these two programs into one by making Program 1 read the array of numbers from the file and then calculate the average using that instead of the array { 84, 92, 76, 81, 56 } as outlined below. I only wish to display the average in the output, not the number array as Program 2 does.
I have tried to do most of the work, I just need modifying the code slightly so it reads the number array from the file and calculates the average.
Program 1
#include <iostream>
#include <cmath>
#include <math.h>
#include <fstream>
#include <string>
#include <numeric>
using namespace std;
int main() {
const int nNumStudents = 5;

How can I calculate the total of pages for all file(pdf,word,excel,txt...) types in a directory with c#?

View 4 Replies View RelatedAs you can see, the code below calculates the average, sum, number of items, etc, for a list of numbers in two separate files and compares them with one another.
e.g. we will have a text file of 10 numbers;
45

The problem is that the code will perform calculations on all the numbers in the txt. or csv. file. This is problematic because if there is any text in the file, e.g. headings, then the calculations will not be performed. For instance, suppose that I only wanted to include rows 5-10 in the calculations, how would I specify this in my C++ code?
#include <iostream>
#include <cmath>
#include <math.h>

#include<fstream>

I have written a C++ program I have multiple of CSV file used as input, which I open one at a time and close it after extracting data to a output file which is the only file.
I run getline(inFile,line);
outFile << line << endl;
I run this code, and only part of it is goes to the output file I got, also have spacing randomly to specific file and inconsistent
But when I slower the code, like system("Pause") in the loop, I can get extract what I want perfectly....
Is my program running to fast, why getline would be skipping part of what things I want?

The problem I'm having now is how to go about passing the grades to the function computeGrade and then compute the average and return that to the function.
how do i decompress an input file and write the results into an output file?
also my do while loop is supposed to keep going unless the user selects the option to exit the program, instead it exits after finishing ay of the options.
here's my code so far...

#include <iomanip>

I have a program where I will read in a certain .txt file, such as "financial_data.txt" and I will be doing some sorting with this data.
I want my program to write out the sorted data to an output file and I want the name of the output file to be based off of the input name. For example, since my input file is "financial_data.txt", I want the output file name to be "financial_data_out.txt".
I am having a hard time finding examples online and in my reference manuals...
I have written this code to remove the comments from an input file and then put it into an output file. The program compiles and runs but it removes the whole line of code when it encounters a /* */ type comment. I believe the problem is in the while loop but I just don't know where.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main(void) {
string infile, outfile;
ifstream source;
ofstream target;
